Fascinating project! I've been following the developments in solid-state batteries for a while now. Have you considered testing it under extreme temperatures or conditions?
john_doe 6 months ago next
@geeky_gabe, great idea! Actually, I've started planning to test it with EV-like conditions. I believe there's an old electric scooter lying around in the garage which I can repurpose.

That's the first thing I would test as well, along with the energy density and lifetime. It would be cool to see it powering an electric vehicle application.

Still, I have concerns about manufacturing costs and potential hazards associated with solid-state batteries. Have you managed to estimate the crossover cost point?
john_doe 6 months ago next
Those are definitely relevant considerations. While I've not performed an in-depth analysis, I believe significant production scaling and research advancements could address these issues.

Have you looked into using alternative materials like perovskites for your electrolyte? It could potentially increase the battery's attractiveness due to lower costs.
john_doe 6 months ago next
@innovator_jane, I haven't specifically tested perovskites, but I am aware of their potential in reducing costs. I'll certainly consider them as I refine the project.

Is there any reason why the liquid/gel-state batteries still lead the market? What do you think is the challenge in commercializing this technology?
john_doe 6 months ago next
@quantum_quokka, it mainly comes down to cost, established manufacturing methods, and the lacking large-scale production of solid electrolytes. I see a shift coming as we progress with R&D.

It's a truly exciting development! Have you seen any notable breakthroughs in self-healing materials to complement your solid-state battery project?
john_doe 6 months ago next
@optics_oliver, quite interesting area indeed. I haven't explicitly investigated self-healing materials, but I can see how this could further enhance the technology. Thank you for bringing it up.

Was thinking of kicking off my own solid-state battery experimentation. Any recommended resources or tips to expedite the progress?
john_doe 6 months ago next
@tinkerer_tom, Materials Research Society (MRS) conferences on solid-state batteries would be an excellent place to start. It helped me observe various approaches and understand what's currently missing.

Excellent, well-articulated overview of your solid-state battery development. I recently came across some work in graphene-wrapped nanoparticles; have you evaluated the feasibility for use in your battery?
john_doe 6 months ago next
@nanoscience_norm, graphene-wrapped nanoparticles are a promising area. I'm considering using them to replace traditional electrode materials, but my experiments are ongoing. Thanks for bringing it up!

Inspirational effort! Would love to know how you approached the mechanical side of these solid-state batteries regarding volumetric changes. Do you worry about potential cracking?
john_doe 6 months ago next
@user21, I'm glad to see a lot of interest in the mechanical aspects. I ran simulations to observe volumetric changes and chose material combinations that create a sufficient buffer zone. So far, so good!

I see you are moving towards a laminated approach, similar to LG's relatively recent step. Would that be a fair assumption, and how is scalability as you compared to conventional pouch cells?
john_doe 6 months ago next
@user23, I see where you're going with that assessment. This project takes inspiration from LG's approach, but I'm more focused on creating a compact and efficient design, initially as a prototype, before even considering production scalability.
